AbstractGraft copolymerization of methyl methacrylate (MMA) on oxycellulose modified with a polyamine diethylene triamine (DETA) was studied in a limited aqueous system under photoactivation in visible light using K2S2O8as the intiator. No polymerization was observed in the dark or in presence of light in 80 min in the case of DETA‐treated cellulose; however, ready graft copolymerization resulting in high percent grafting and grafting efficiencies took place in the case of DETA‐modified oxycellulose system under photoactivated conditions. DETA‐modified oxycellulose prepared from oxycellulose corresponding to low degrees of oxidation (copper nos. 1.5–3.5) produced optimum grafting. The grafting parameters under different sets of conditions were studied and compared, and the mechanism of graft copolymerization was di
